No. Those speakers you have now have 15" woofers in them, those Sony's are really not worth the money. I would say go for a pair of bookshelves and sub woofer.
You could get the Pioneer BS22 bookshevles and a BIC America F-12 for about $300, and it would sound much better than those Sony's.
If you want those big 3-way speakers like you had, check out Craigslist. That kind of speaker is very rare nowadays, the trend is more smaller woofers.
